BAIL-JOINT.

Application led September 24, 1917.

, To all whom, it may concern.'

A the following to he a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to certain new and useful improvements in rail joints, and has for its object to provide a device of this character which embodies novel features of construction whereby the abutting ends of a pair of rails can be held Securely against hoth vertical and lateral displacement relative to each other. without the necessity of employing the usual splice bars.

Further objects of the invention are to provide a rail joint which is'comparatively simple and inexpensive in its construction, which holds the rail ends securely together and will not work loose under the vibrations incident to heavy traffic, and which is not liable to shear or break in the event of derailment.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is .to be had to the following description and accompanying drawing, in which `Figure 1 is a side elevation of a rail joint constructed in accordance with the invention.

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

. Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is a horizontal sectional view taken ,on the line 4-4 of Fi 3. Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, which illustrate one embodiment of the invention, the numerals 1 and 2 designate the abutting ends of a pair of rails which are preferably of the standard' cross section. The rail 1 is provided upon opposite sides of the web there- Specification of Letters Patent.

of and also upon the upper surface of the basal flanges with integral outstanding longitudinally extending ribs 3, said ribsbeingprovided with the threaded boresli. The ribs 3 on the web of the rail are preferably located adjacent the head thereof, while the ribs 3 on the base flange thereof are prefn erably located adjacent the web, and the hores al. may have the inner sides thereof extending into what would be the regular cross section of the rail, thereby avoiding the necessity of making the ribs unnecessarily thick. vThe rear ends of the threaded bores 4 in the ribs 3 are preferably closed so as to exclude dust and dirtI therefrom. The opposite rail end Q is provided with ribs 5 which correspond to the ribs 3 of the rail 1, said ribs 5 being provided with bores 6 which extend entirely through the saine from end to end. These ribs 5 are provided at intermediate points in their lengths with side openings 7 which intersect the bores and are adapted to provide a clearance space for the reception of a wrench or similar tool. The portion of the bores 6 between the end of the rail and the side opening 7 are threaded, while the rear ends of the bores are not threaded. Bolts S are threaded in the bores 6 of the ribs 5 and the bores 4t of the corresponding lribs 3 to hold the rail ends securely together and prevent relative dis placement thereof. These bolts 8 are each threaded for approximately two thirds or three fourths of their length from one end thereof, the opposite end of the bolt being square, as indicated at 8, for engagement with a wrench to rotate the bolts. The bolts or rods 8 are inserted in position through the open rear ends of the ribs 5 on the rail ends 2 and screwed through the threaded portion of the ribs until they are flush with the ends of the rail 2, whereupon the end of the rail 1 is caused to abut against the rail Q and the bolt or rod 8 threaded into the bore of the corresponding rib 3 on the rail 1 by continued rotation thereof. rlhe side openings 7 in the ribs 5 enable the square ends 8a of the bolts to be readily engaged by a wrench for manipulating the bolts at any time, and the arrangement is such that the rail ends will be held securely together, even though there might be a. slight loosening of the bolts. If desired, doors or closures 9 which are mountedupon the' spring hinges 10 may be provided for the side openings 7 of the ribs, said doors serving to exclude faces 9 tiisieof n squame (if polygonal u iss im Esci-z them agaiiiss accidental staoii. it will be undsssod, soif/Msi,
